Abstract: Edges, hems, patches and seams for woven fabric that has been treated for water repellency, and methods for making the same, are shown and described. In one particular embodiment of the invention, for example, a lapped seam between two pieces of water repellent fabric has an outer material at least partially overlapping an inner material, and a laminate strip positioned between the overlapping portions of the materials. The outer and inner materials, which are both oriented in the same direction, have an exterior layer of woven fabric that has been treated with water repellent and/or stain repellent chemicals, and an inner layer comprising a polymer membrane, such as polyurethane. The laminate strip has a bottom portion in contact with the outer layer of the inner material.

Title: Microarray synthesis instrument and method
Inventor: GREEN ROLAND
IPC: C40B40/06
Filed: 2003-01-28
Granted: 2011-10-04
Abstract: During the light illumination period of a monomer addition cycle in synthesizing an DNA microarray, undesirable reflections of illumination light from various interfaces that the illumination light passes through near the synthesis surface of the substrate may reduce the light dark contrast, and negatively affect the precision and resolution of the microarray synthesis. The present invention provides an flow cell that reduces the undesired reflections by constructing certain flow cell structures with materials that have similar refractive indexes as that of the solution that is in the oligomer synthesis chamber during the illumination period and/or constructing certain flow cell structures or covering the structures with a layer of a material that has a high extinction coefficient.

Abstract: A method of predicting the composition of hydrocarbon products of a complex carbonaceous material when exposed to specific time and temperature conditions is disclosed. In one embodiment, the material is characterized to obtain elemental, chemical and structural parameters. A representative chemical structure of the material is constructed based on the characterization information.

Abstract: L'invention concerne un procédé d'incorporation d'une matière dans un liant durcissable. Le liant comprend une source d'oxyde de magnésium caustique. Ledit procédé consiste à mélanger la matière avec le liant, soit en tant que partie d'une suspension épaisse soit en vue d'une transformation ultérieure en suspension épaisse, et à ajouter un accélérateur de prise à la suspension. Ledit accélérateur de prise est ajouté pour accentuer le durcissement du liant. La matière peut être un déchet dangereux ou un composant de celui-ci. Les inventeurs ont découvert avec surprise que lorsque l'accélérateur de prise est ajouté après le mélangeage de la matière avec le liant, un durcissement supérieur de la matière dans le liant peut être obtenu. Ladite composition durcissable peut comprendre uniquement un liant à l'oxyde de magnésium caustique et un accélérateur de prise pour le liant, car les inventeurs ont découvert contre toute attente qu'il n'est pas nécessaire d'utiliser un agent de liaison, quel qu'il soit, ce qui permet la production d'une composition de liaison et un procédé d'utilisation plus simples.

Abstract: An implantable device, such as an infuser device for bi-directional hydraulically controlling a medical artificial sphincter, enhances power transfer characteristics to a secondary coil thereby allowing implantation to greater physical depths and/or enclosing the secondary coil within a housing of the infuser device. The enhanced power transfer is achieved with multiple coils that are longitudinally aligned and physical and electrical parallel to form the secondary loop of a transcutaneous energy transfer system (TET) instead of a single coil. It better optimizes the power transfer from a parallel tuned tank circuit primary coil to an implanted secondary series tuned tank circuit coil.

Title: Catheter with limited longitudinal extension
Inventor: VITULLO JEFFREY M

Granted: 2010-11-09
Abstract: A catheter includes a tube formed of plastic, a helical spring coil formed of metal and a ribbon which is longitudinally substantially non~-extendable. The coil is coaxially disposed within the tube and substantially coextensive longitudinally with the tube. The ribbon is disposed within the coil, proximal ends of the ribbon and the coil being secured together, and the ribbon distal end being secured to the coil body at a predetermined point of the coil body adjacent but substantially proximally spaced from the coil distal end. The ribbon precludes substantial longitudinal extension of the coil body intermediate the coil proximal end and the predetermined point, thereby to limit longitudinal extension and increase the pull strength of the catheter.

Title: Reinforced insulated forms for constructing concrete walls and floors
Inventor: AMEND VICTOR
IPC: E04B5/36
Filed: 2005-10-26
Granted: 2014-08-12
Abstract: A panel for a building form made of insulating material such as polystyrene is integrated with a reinforcing member for enabling the panel to resist deformation due to forces applied against its concrete-facing surface. Reinforcement of floor/roof panels is beneficial to reduce the amount of, or eliminate the need for, shoring for supporting the weight of wet concrete or workers. The reinforcement resists against deformation due to cracking, splitting etc. Reinforcement is likewise beneficial for wall forms where the weight of concrete asserts significant pressure against the concrete-facing surface of the form, in order to resist deformation of the wall forms under pressure. The reinforcing member may be made of a plastic material such as polypropylene or high-impact polystyrene. Methods of manufacturing reinforced form panels are disclosed.
